Fast file editing via Morph Apply API (10,500 tokens/sec, 98% accuracy)

  • Calls uv; needs MORPH_API_KEY

What it does

Morph Apply is an agent skill from parcadei/Continuous-Claude-v3. Fast file editing via Morph Apply API (10,500 tokens/sec, 98% accuracy)

Its SKILL.md is about 740 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows. The repository describes itself as: Context management for Claude Code. Hooks maintain state via ledgers and handoffs. MCP execution without context pollution. Agent orchestration with isolated context windows. The licence is MIT.

When your agent uses it

  • Agent Workflows work in your project

Example prompts

  • “/morph-apply”

Requirements

  • Python 3
  • A credential in MORPH_API_KEY
  • Pre-approved tools (allowed-tools): Bash, Read

What it can do on your machine

Read from SKILL.md and the folder at commit d07ff4b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash
    • Read

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • uv

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • MORPH_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Morph Apply loads about 739 tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 244 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~21
When it runs · the whole SKILL.md, loaded when a task matches
~739

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Bash, Read

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Morph Fast Apply

Fast, AI-powered file editing using the Morph Apply API. Edit files without reading them first. Processes at 10,500 tokens/sec with 98% accuracy.

When to Use

  • Fast file edits without reading entire file first
  • Batch edits to a file (multiple changes in one operation)
  • When you know what to change but file is large
  • Large files where reading would consume too many tokens

Key Pattern: Code Markers

Use // ... existing code ... (or language-appropriate comments) to mark where edits go:

python
# ... existing code ...
try:
    result = process()
except Exception as e:
    log.error(e)
# ... existing code ...

The API intelligently places your edit in the right location.

Usage

Add error handling
bash
uv run python -m runtime.harness scripts/mcp/morph_apply.py \
    --file "src/auth.py" \
    --instruction "Add error handling to login function" \
    --code_edit "# ... existing code ...
try:
    user = authenticate(credentials)
except AuthError as e:
    log.error(f'Auth failed: {e}')
    raise
# ... existing code ..."
Add logging
bash
uv run python -m runtime.harness scripts/mcp/morph_apply.py \
    --file "src/api.py" \
    --instruction "Add debug logging" \
    --code_edit "# ... existing code ...
logger.debug(f'Processing request: {request.id}')
# ... existing code ..."
TypeScript example
bash
uv run python -m runtime.harness scripts/mcp/morph_apply.py \
    --file "src/types.ts" \
    --instruction "Add user validation" \
    --code_edit "// ... existing code ...
if (!user) throw new Error('User not found');
if (!user.isActive) throw new Error('User inactive');
// ... existing code ..."

Parameters

ParameterDescription
--fileFile path to edit (required)
--instructionHuman description of the change (required)
--code_editCode snippet with markers showing where to place edit (required)

vs Claude's Edit Tool

ToolBest For
morph-applyFast edits, don't need to read file first, large files, batch edits
Claude EditSmall precise edits when file is already in context

Use morph-apply when:

  • File is not in context and reading it would be expensive
  • File is very large (>500 lines)
  • Making multiple related edits at once
  • You know the context of the change (function name, class, etc.)

Use Claude Edit when:

  • File is already in context from prior Read
  • Very precise edits requiring exact old/new string matching
  • Small files (<200 lines)

MCP Server Required

Requires morph server in mcp_config.json with MORPH_API_KEY.

Performance

  • Speed: 10,500 tokens/sec
  • Accuracy: 98% correct placement
  • Token savings: Don't need to read entire file first
